Macaroni!

"The touching story of a child, Romeo, getting to know his grandfather, Ottavio, an Italian immigrant living in Belgium. But there are some
surprises in store for Romeo during his visit. Ottavio , beneath his old, grouchy exterior, conceals the hard life he has led, full of
suffering and sacrifice. It started off as just a short holiday to a grey Belgian town. But this holiday turns into an opportunity for three generations of men to lift the silence that surrounds them. A touching story about Italian immigration, coal mining, communication between the generations and the difficultly in talking when you've spent your whole life in silence."
